φ- meson Production at RHIC energies using the PHENIX Detector
Light vector mesons are among the most informative probes to understand the strongly coupled Quark Gluon Plasma created at RHIC. The suppression of light mesons at high transverse momentum, compared to expectations from scaled p + p results, reflects the properties of the strongly interacting matter formed. The φ-meson is one of the probes whose systematic measurement in p + p, d + Au and Au + ...
متن کاملStrange quark collectivity of φ meson at RHIC
Based on AMPT model, the elliptic flow v2 of φ mesons which is reconstructed from KK at the Relativistic Heavy Ion Collider (RHIC) energy has been studied. The results show that reconstructed v2 of φmeson can keep the earlier information before φ decays and it seems to obey the number of constituent quark scaling as other mesons and baryons. This result indicates that the φ v2 mostly reflects t...
متن کاملSystem size and energy dependence of φ meson production at RHIC
We present a system size and energy dependence of φ meson production in Cu+Cu and Au+Au collisions at √ sNN = 62.4 GeV and 200 GeV measured by the STAR experiment at RHIC. We find that the number of participant scaled φ meson yields in heavy ion collisions over that of p+p collisions are larger than 1 and increase with collision energy. We compare the results with those of open-strange particle...
متن کامل(Strange) Meson Interferometry at RHIC
We make predictions for the kaon interferometry measurements in Au+Au collisions at the Relativistic Heavy Ion Collider (RHIC). A first order phase transition from a thermalized Quark-Gluon-Plasma (QGP) to a gas of hadrons is assumed for the transport calculations. The fraction of kaons that are directly emitted from the phase boundary is considerably enhanced at large transverse momenta KT ∼ 1...
متن کاملAzimuthal anisotropy of φ meson in U+U and Au+Au collisions at RHIC
The measurements of the azimuthal anisotropy of φ meson in the U+U and Au+Au collisions at the Relativistic Heavy-Ion Collider (RHIC) are reported. The centrality dependence of the Fourier coefficients v2, v3, v4 and v5 is presented for φ meson at midrapidity (|η| ≤ 1.0), in U+U and Au+Au collisions at sNN = 193 and 200 GeV, respectively. The η-sub event plane method is used with a η gap of 0.1...
